Multiple laser laser level

Abstract

A laser level which projects one to four laser lines on surfaces capable of reflecting light within a projection envelope around the laser level such that the lines can provide plumb, level, and/or other guide lines on any surface facing the laser level within the projection envelope of the laser level.

1 . A device for providing guidelines comprising: 
 a housing;    at least two pods attached to the housing and moveable with respect to the housing, each pod having a light source for projecting a guideline of light through a respective point on a respective surface;    a first adjustor for each pod to locate the respective point on the respective surface; and    a second adjustor for each pod to rotate the respective guideline through the respective point.    
     
     
         2 . The device of  claim 1  wherein at least two of the pods project the respective points at a right angle with respect to each other.  
     
     
         3 . The device of  claim 1  wherein the first adjustor comprises: 
 an attitude control for moving the pod with respect to the housing.    
     
     
         4 . The device of  claim 1  wherein the second adjustor comprises: 
 a lens for converting a beam of light from the light source into a guideline;    a frame for supporting the lens; and    a rotation control for rotating the frame.    
     
     
         5 . The device of  claim 1  further comprising: 
 a rotatable base having a first section which attaches to the housing, a second section for placement on a surface, and a rotation mechanism to allow the first section to rotate with respect to the second section.    
     
     
         6 . The device of  claim 5  wherein the rotatable base further comprising one or more pin units, each pin unit comprising: 
 one or more pins for connection to the surface on which the base is placed; and    an actuator for moving the pins from a retracted position inside the second section to an extended position such that the pins can penetrate the surface.    
     
     
         7 . The device of  claim 5  further comprising a suction cup unit comprising: 
 one or more suction cups for connection to the surface; and    a suction cup connector for connecting the suction cup to the base.    
     
     
         8 . The device of  claim 5  wherein the first section further comprises: 
 an attachment device for releasable attaching the housing to the first section.    
     
     
         9 . The device of  claim 8  wherein the attachment device comprises one or more magnets.  
     
     
         10 . The device of  claim 5  further comprising: 
 stops at certain angles of the rotation of the first section with respect to the second section.    
     
     
         11 . The device of  claim 5  further comprising a measuring device.  
     
     
         12 . The device of  claim 5  wherein the first section further comprises a level which indicates the true level of the base.  
     
     
         13 . The device of  claim 1  wherein the housing further comprises a level which indicates the true level of the housing.  
     
     
         14 . The device of  claim 1  wherein the housing further comprises: 
 a switch to activate any combination of the light sources; and    a source of power.    
     
     
         15 . The device of  claim 13  wherein the source of power are batteries provided inside the device.  
     
     
         16 . A method of using a device for providing level lines which has a housing, at least two pods attached to the housing and moveable with respect to the housing, each pod having a light source for projecting a guideline of light through a respective point on a respective surface, a first adjustor for each pod to locate the respective point on the respective surface; and a second adjustor for each pod to rotate the respective guideline through the respective point, comprising the steps of: 
 placing the housing on a first surface;    adjusting each pod with each respective first adjustor to locate a respective point on a respective target surface; and    adjusting each pod with each respective second adjustor to rotate the respective guideline to a desired position.    
     
     
         17 . The method of  claim 16  further comprising the steps of: 
 attaching the housing to a base, the base having a first section rotatably connected to a second section; and    rotating the first section with respect to the second section to position the pods.    
     
     
         18 . The method of  claim 17  wherein the step of placing the housing on the first surface comprises the steps of: 
 engaging an activator in the base to move pins from a retracted position inside the second section to an extended position so that the pins can penetrate the first surface.    
     
     
         19 . The method of  claim 17  wherein the step of placing the housing on the first surface comprises the step of: 
 attaching a convex side of a suction cup to the base and the concave side of the suction cup to the first surface.    
     
     
         20 . The method of  claim 16  wherein the step of placing the housing on the first surface comprises the steps of: 
 attaching a tripod base to a tripod;    adjusting the tripod base to be at true level; and    attaching the laser level to the tripod base.
